Performance bike has much better 100psi 27" tires, usually on sale under $10. If you have one of their stores nearby they match online prices with no shipping charge. This weekend they had Kevlar 27 inchers for 9.95 less 20% with coupon from website. They have 1" and 1x1/8" as well as 1x1/4". Not gumwalls but Performance often sponsor these forums.
